WITNESS ATTORNEY lowing, detailed description is read in hal ll ,iltl tlhtll'ltu Application filed June 1, 1920.

To (11/ who: if may roam r11 lle it known that l. Aurzo llanx, a citizen of the United States. residing at lloulder, in the county of Jefferson and tit-ate of lilo tana. have invented new and useful lm-. provements in Water-tirculators, of which the following is a specification.

This invention relates to the cooling system of motor operated vehicles, and comprehcnds a device which can be readily and easily installed on any make of ear, the device being operable to assist in circulating the water on its prescribed course, maintaining the motor at ainore uniform and low temperature, thus )reventing the engine from overheating w iichlnaterially reduces theelliciency of a motor. 7

More specifically stateih the invention makes use of a propeller operated from the fan belt of the motor, the propeller being; disposed in the connection between the radiator and the water jacket ofthe motor, the propeller operating to increase the low or circulation of the water-for the purposes above mentioned.

The nature and advantages of the invention will be better understood when the folcon nection with the accompanying drawng, the

invention residing in the (()llSt1llt'tl()1L combination and claimed.

in the drawings forming part of this application like numerals of reference indicate similar parts in the several views, and wherein Figure l is a 'lragnnentarv view of the forward end of a motor vehicle, showing the relative position of the invention with respect to the radiator, water-jacket of the motor and the fan belt.

Fig. 2 is an enlarged sectional view taken through the combined water and propelling casing-21ml the bearinp for the propeller shaft.

vehicle, ill the fan belt, and C the water iin-l let to the water-jacket of the engine.

i The device forming the subject matter of my invention comprises a combined wateif and propeller casing indicated at D, an made up of two sections 10 and 11 respectively, each of which has an annular flange arranged in face to face contact and secured together by means of fastening elements 12. This casing is arranged between the water outlet ()Pfillillg of the 'adiator, and the water inlet opening of the water-jaeket, providing a connection between these parts, to which the casing l) is secured by means of short lengths of hose 13 and hose clamps 14 of usual construction. The section 10 of the casing l) is formed with an offset portion 15 having a bore 16 opening at one end into the casing; l), and at its upper end above the casing", the bore being interlorly threaded for a portion of its length as at 17 Threaded into this-bore is a sleeve like member 18 constituting; a bearing for the shaft 19, the shaft passing through a packing gland 20 secured to one end of the sleeve as shown.

The sleeve is provided with an aperture through which oil or other suitable lubricant may be introduced, the opening being normally closed by a plug 21. The sleeve 18 projects a slight distance within the easing it), while the shaft 19 passed through the sleeve projects within the casing and supports a propeller 22 of any suitable con struction. 'llheopposite end of the shaft 19 supports a cone shaped pulley 24 which is arranged at one. side of the fan belt B and engaged by the latter, so that when the motor is in operatioin rotation is imparted to the shaft 15) through the instrumentality of the fan belt. in Figs. 1 and 2, the pulley 2+1- is shown arranged at that side of the fan belt, so that the shaft 19 is rotated toward the left, and if found necessar to rotate the shaft in the opposite direetion,. the pulley 24 can be arranged at opposite side of tho the fan belt for rotating the propellershaft belt as illustrated in Fig. 4. I

ln practice, the casingvD is arranged between the outlet end oftlie radiator and the inlet end of the water-jacket of the motor, and held in position by the clamps and hose connection as shown. When the motor is in oaeration, the pulley Qtcontacting the fan elt lB, causes the shaft 19 to rotate, and as the propeller 29: is arranged within the water casing lD it fOrCeStl e water through the casing from the radiator to the inlet opening of the Water-jacket. The propeller operates to materially assist the circulation of water through the entire cooling system. and by reason of the fact that the water casing and the propeller casingz'are combined, there is provided sufficient by-pass for the water to flow by the thern1osiph n action. should the propeller at any time fail to work. The invention is particularly advantageous in maintaining a more uniform and low temerature of the motor, thus preventing overeating of the motor and boiling over of the radiator. The rapidity with which the propeller is actuated, may be controlled h set ting the pulley 24 so that the fan belt B will contact more or less of its circumferonce.

While it is believed that from the foregoing description, the nature and advantages of the invention will he better understood, I desire to have it understood that I do not limit myself to what is herein shown and described. and that such rhanges may he resorted to when (lQSll'Od as fall within the .scope of what is elairned.

\l'hat I claim is;

The conihination with a water cooled enginc of a motor vehicle. of a substantially iuhular ineniher interposed between the out let oi' the radiator and the inlet of the water jacket. an ohliquoly disposed portion of said member constituting a hearing. a shaft journaled in said hearing and pr jecting from said member in the direction of the {an hell. 'pulley. a cone-shaped pulley carried hr the free end of said shaft and arranged to he driven by the fan belt. and a propeller carried by the opposite end of the sha ft and op erating in said tubular member for the purpose specified.

in testimony whereof I atiix niy signa' ture.
